Letters Patent No. 106,119, dated August 9, 1870.

IMPROVEMENT IN RAILWAY CAR-COUPLING.

the Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I Sonox O. CAMPBELL, ofGent-retown, in the county of Cole and State of Missouri,

have invented a new and improved Oar-Coupling; and

I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being bad tothc accomrnmying drawing formingpart of this specification, in which- Figure 1 represents a verticallongitudinal section of my improved ear-couplin".

Figure 2 is a vertical transverse section of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to improvement in car-couplings, such as are usedwithout a link, and consists in the-construction and arrangement ofparts as hereinafter described.

A A, in the drawing, are two coupling-boxes of suitable size and shape,made of cast-iron or other suitable material. The frol'lt'endol' eachhas two or 'more tbrward projecting plates, to a, with rounded -1'rontedges, the spaces between. every two plates, (1,

being just large enough to admit one such plate from the oppositebox,'as shown.

In the front partof each box A. is arranged a lever, B, which is fittedthrough slots of the box and held down by a projecting pin, 5, so thatit may swing in the slot.- 7

Its horizontal upper arm contains a sliding couplingpin, 0.

The lever can swing back on its'pivot, I), and is thus swung backprevious to coupling, while the pins are drawn up as far as possible.

When two boxes, A A, are pushed together to have their plates tointerlocked like fingers, the lever B of the higher box will be pushedinto a vertical position tomake its pin 0 drop, while the other lever Bwillj be held back by the upper plate (a of the higher box,

as shown in fig. 1.

The pin G of the higher box will drop through up ertures of all theplates A, and will therefore effectually lock the boxes together.

This coupling can be used without a link, but may also be workedtogether with the same if desired.

Having thus described my invention,

1 claim as new, and desire to secure by Letters Patcnt-- The fingers aof the boxes A, levers B 13, and pins 0 0, when said parts areconstructed and relatively: arranged as shown and described.

Witnesses: SOLON '0. CAMPBELL.
